Growth curves for E. faecalis V583 (continuous line) and E. faecalis V583 ΔagdiΔtdc (discontinuous line) in media supplemented with 20 mM agmatine and 10 mM tyrosine. (A) influence of putrescine and tyrosine synthesis on cultures grown in GM17. (B) effect of limiting the carbon source on cells cultured in M17 supplemented with glucose at 1 g L−1. (C) influence of acidic pH on the growth of strains propagated in GM17 adjusted to an initial pH of 5.0. (D) growth under a combination of carbon source depletion and acidic pH in M17 with glucose 1 g L−1 and pH adjusted to 5.0. The OD600 was monitored over 10 h.
